Component: Vortex flow control

Description

A self-activating device that provides improved hydraulic performance over conventional flow controls such as orifice plates and throttle pipes and reduced maintenance requirements.

It consists of an intake, a volute and an outlet. Flow is directed tangentially into the volute to form a vortex. High peripheral velocities induce an air-filled core with resulting back pressure that reduces the rate of discharge of the flow.

Reduces upstream storage requirements

Adjustable versions available to provide future-proofing

Reduces risk of blockage

Minimal maintenance requirements

More expensive than orifice plates or throttle pipes

May require confined space entry if removal or replacement is required
